In his third lecture on the philosophy of life and death, Shelly Kagan begins presenting and refuting arguments for the existence of a supernatural or immaterial soul, or what he calls the "dualist perspective". He explains that one argument for the dualist perspective is that a supernatural or immaterial soul is required to explain the sorts of capacities that humans exhibit. He then appeals to technological advances, particularly computers and robots, to demonstrate that many of the capacities attributed to humans are already exhibited in bodies to which we do not attribute dualist natures. He ends by mentioning that he'll explore in the next lecture whether computers or robots might have the capacity for emotion.
In a study at Bright University, a majority of test subjects given a particular pattern of brain stimulation had full-blown dog experiences. Such research is shedding light on the chemical reactions that take place in the brain when people feel they are encountering dogs.
Some have criticized Mormon Transhumanists, or even scientific- and technologically-leaning Mormons generally, as "looking beyond the mark" and not relying enough on faith, grace, priesthood, revelation, spirituality, God or something else presupposed to be at odds with science and technology. This criticism is entirely inconsistent with Mormonism, as I discuss a bit more in this post.
A couple months ago, my wife and I started taking resveratrol, a dietary supplement that appears to be effecting significantly extended and healthier life spans in mice and monkeys. Results have not yet been verified in humans, but here's a video segment from 60 minutes that may intrigue you.
In this lecture, Shelly Kagan talks about life and death, as well as persons, in black and white terms. However, are there degrees of life and death? Are there degrees of consciousness? Are there degrees of identity?
I've begun watching Shelly Kagan's lectures on the "Philosophy of Life and Death" via Academic Earth, which links to thousands of video lectures from the world's top scholars. In this set of lectures, Shelly argues for the following perspective: "I'm going to try to convince you that there is no soul. Immortality would not be a good thing. Fear of death isn't actually an appropriate response to death. Suicide, under certain circumstances, might be rationally and morally justified."
